,This invention Vrelates to line tappers. The object of the invention is the production of a simple and veiicient device for mals l ing connections on high voltagewires.

Anotherobject of the invention is the construction of a line tapper, which can beeasily connected to or fastened upon high voltage wires by means of operating devices.

With these and other objects in view, myy

Figure 2 is a view in. side elevation of the i line tapper. i

Figure 8 is" a vertical,V central sectional view of the line tapper.

Figure 4 is a View in rear elevation of the line tapper.

Figure 5 isa sectional view taken on line 5 5, Figure 2, and looking in the direction of the arrows. Y

Figure 6 is a sectional view taken online 6--6, Figure 5, and looking in the direction of the arrows.

Figure 7 is a perspective view of the auxiliary jaw.

Referring to the drawings by numerals, 1, Fig. 1, designates my line tapper, 2 is the operating device, and 8 is the hook device.

My line tapper 1 comprises a primary jaw 4, upon which is mounted movable auxiliary jaw 5. The primary jaw 4 comprises a vertical body 6 that has an elongated inverted substantially U-shaped upper end 7. The

` auxiliary jaw 5 comprises a plate-like hori- Zontal body 8, supported upon the upper end of angle, flat spring 9; the upper end of spring 9 is set into the body 8 as clearly shown in Figure 7 with the lower end fastened by screws 10 against the inner face of body 6. In the inner face of body 8 is a longitudinally extending socket11 for receiving the wire 12, Figure 1. In the upper edge of body 8 are transverse sockets 18, 18. On the inner face of the upper end of the primary jaw is a horizontal socket 11a that registers with socket l11. I employ two special screws 14; each screw 14fis provided with a spindle 15 (Fig. 6)',having one end seated in socket 16 and at its other end is an enlarged threaded portionl?. The spindles 15 of screws 14 are positioned in the transverse sockets or notches 18,1011 the purpose of preventing wire 12 `from going too far up in my line tapper. In otherwords, these screws 14 make itpos sible for wire 12 to be quickly'seated in the socketsor Vgrooves 11 and 11a; also, the spindles 15 of screws 14 prevent any injurious end-wise play oi the auxiliary jaw 5, keeping. said jaw properly centered at all times upon the primary aw `and thereby producing a very efficient device. e Y

'A cam 18 is pivotally mounted at 19 upon the primary jaw, with its inner end extending into said j aw against the spring 9 of the auxiliary 5, whereby when hook device 3 (Fig. 1)V is hooked into the aperture or eye 2O in the outer end of cam 18, and a downward pull is exerted" upon the hook device 8, the cam 18 will bepressed against `the auxiliary aw, thereby causing the body 8 to tightly clamp wire 12 within the sockets 11 and 11a.

A wire 21 is connected, at 22, to the lower end of primary jaw 4.

When my line tapper 1 is mounted upon the operating device 2,l it can be quickly placed upon a wire such as 12, and then through the use of khook device 8, the line tapper can be l securely `fastened upon the wire. The detail' structure of operating device 2 is illustrated and described in my United States Patent No. 1,687 ,584, issued October 16, 1928.

It is to be understood that the cam 18 is pivotally mounted in anelongated slot 23, formed in the body 6 of the primary jaw 4 Fig. 3).

While I have described the preferred embodiment of my invention and illustrated the i same in the accompanying drawings, certain minor changes or alterations may appear toV one skilled in the art to which this invention relates during the extensive manufacture of to make such changes or alterations as shall fairly fall Within the scope of the appended claims.

What I claim is:

l. In a line tapper, the combination of a primary jaw provided with an upper Wirereceiving end, said Wire-receiving end provided on its inner face With spindle-receiving sockets, screws provided With spindles on said upper Wire-receiving end of the primary jaw With said spindles in said spindle-receiving sockets7 a movable jaw on said primary jaw contiguous to said spindles, and an operating cam on said primary jaw and normally engaging said auxiliary jaw.

2. In aline tapper, the combination of a primary jaw provided With an upper Wirereceiving end, said Wire-receiving end provided on its inner face with a pair of spindle-receiving sockets, a pair of screws comprising spindles with enlarged threaded outer portions, said threaded outer portions threaded into said jaw with the inner ends of said spindles seated in said spindle-receiving sockets, a movable jaw on said primary jaw, said movable jaw provided near its ends With transverse sockets in which said spindles are positioned, and a cam ony said primary jaw and operatively engaging said movable jaw, substantially as shown and described;VK

In testimony whereof I hereunto affix my signature.

EDWIN B. NORMINGTON.
